Question

1. if the current coming out a battery is 2 a, calculate how much charge will come out of the battery in 1 hour.

Explanation:

Step1: Identify given values

$$I = 2\text{ A},\quad t = 1\text{ hour}$$

Step2: Convert time to seconds

$$t = 1 \times 3600\text{ s} = 3600\text{ s}$$

Step3: Calculate the charge

$$Q = I \times t = 2\text{ A} \times 3600\text{ s} = 7200\text{ C}$$

Answer:

\(7200\text{ C}\)
